Which term describes the observable traits of an organism?

• A. Genotype
• B. Phenotype
• C. Allele
• D. Genome

Answer: (B)

Phenotype is the observable traits of an organism. It shows what you can actually see or measure, like height, eye color, or leaf shape, and it results from how the genetic information (genotype) is expressed in the organism, often also influenced by the environment. The genotype is the set of genes an organism carries, not what you directly observe. An allele is a variant form of a gene that can contribute to differences in traits, while the genome is the entire collection of an organism’s genetic material. So the trait-level description being asked for is phenotype.
